FI data collection

I'm working on collecting data for balancing the FI nozzles in the RV-10.

I've been following the procedures in from airflow performance's web site.

The plane is equipped with an AFS 3500, the old style flow meter in the tunnel (flow-scan, I believe - not a red cube), and a quadrant style (non-vernier) mixture control.

I'm struggling to get data every 0.2gph

I can't get the mixture control to move in increments of 0.2gph
On previous x-c flights, the fuel flow settles down and is steady, but I'm really having trouble getting good numbers in these increments (or even something close, 0.3 or 0.4)

Any suggestions??

Thanks
